On last night's episode of her Bravo show Don't Be Tardy, the 35-year-old reality star confirmed she's expecting another child with footballer husband Kroy Biermann.

How'd the couple find out about the big baby news? Let's just say there were over a dozen pregnancy tests involved!

"Pregnant, pregnant, pregnant, pregnant, pregnant, pregnant," Zolciak said during the show as she read the results of a bevy of at-home tests alongside her hubby. "Kroy, we have not one negative test."

"Oh my god. How exciting is that, love muffin?" she gushed while embracing Biermann. "You did it again, lovey...are you excited love muffin? It must be the athlete sperm."

Zolciak and Biermann already have two sons together, Kroy Jr., 2, and Kash, 9 months. She also has two daughters from a previous relationship, Brielle and Ariana.

"I personally would love a little girl because Brielle's going to be 18 soon, Ariana's six years away from being 18," Zolciak admitted on the show, adding, "and I'll be in a house with three boys possibly and Kroy? That's a life of four-wheelers and football."

She added to Biermann, "This is it though, buddy. You better hope you get a little girl, because this is it."

It was reported earlier this month that the couple was expecting their third child together, but it hadn't been confirmed until now. The former Real Housewives of Atlanta star married Biermann in Atlanta on Nov. 11, 2011 (that's 11/11/11).

Biermann legally adopted both Brielle and Ariana as his children, making for one big happy family. "Am I not the luckiest girl in the world!!!!!!??? My girls @BrielleZolciak @arianazolciak are officially adopted by Kroy!!!!" Zolciak recently posted on Twitter. Biermann also tweeted, "One of the happiest days of my life was the day that @BrielleZolciak @arianazolciak legally became mine!! I love you girls!!"

Congrats, you two! Check out the cute clip of the couple finding out about the pregnancy below!
